Lanzol 30 is a prescription capsule containing Lansoprazole 30mg. Belonging to a well-established class of medicines, Lansoprazole is recognised as a proton pump inhibitor (PPI). Acid reflux, GORD, stomach ulcers, and other digestive conditions are among the indications for which it is prescribed. By targeting the acid-producing mechanism in the stomach, the amount of acid generated is significantly reduced.
How Lansoprazole Works in the Body
Embedded within the stomach lining are specialised cells that house microscopic structures called proton pumps. Hydrochloric acid is released into the stomach by these pumps. Although acid plays an essential role in digestion, excess production leads to damage in both the stomach lining and the food pipe.
Lansoprazole works by directly blocking the proton pump enzyme at its source. This significantly and permanently reduces acid production. Unlike antacids, which neutralise acid after it forms, Lansoprazole prevents it from being produced in the first place.
With less acid present, inflamed or damaged tissue can heal. As acid levels are brought down, symptoms like heartburn and regurgitation are gradually relieved. Most patients notice relief within two to three days of starting treatment.
To achieve the most effective result, taking Lanzol 30 at least 30 minutes prior to a meal is strongly advised. The capsule must be swallowed whole, accompanied by a glass of water. Crushing or chewing the capsule alters its release mechanism, which in turn disrupts how it is absorbed.
UK Brand Reference
A number of different brand names are used across the UK to market Lansoprazole 30mg. The table below compares Lanzol 30 with the UK reference brand, Zonton FasTab.
| Feature | Lanzol 30 | Zonton FasTab |
|---|---|---|
| Active Ingredient | Lansoprazole | Lansoprazole |
| Strength | 30 mg | 30 mg |
| Formulation | Hard capsule (delayed-release) | Orodispersible tablet (dissolves on tongue) |
| Drug Class | Proton Pump Inhibitor (PPI) | Proton Pump Inhibitor (PPI) |
| Prescription Status | POM (Prescription Only Medicine) | POM (Prescription Only Medicine) |
| Therapeutic Use | Acid reduction, ulcer healing, GORD | Acid reduction, ulcer healing, GORD |
| Key Differentiator | Standard oral capsule — must be swallowed whole | No water needed — ideal for dysphagic patients or on-the-go use |
Both medicines contain the same active ingredient and work in the same way. Your doctor or pharmacist will advise which formulation is most appropriate for you.
Clinical Uses
UK doctors prescribe Lanzol 30 for the following conditions:
- Gastro-oesophageal reflux disease (GORD) — because acid flows back into the food pipe in GORD, heartburn and regurgitation are commonly experienced as a result
- Oesophagitis — inflammation and damage to the oesophagus caused by chronic acid reflux
- Stomach and duodenal ulcers — open sores in the stomach lining or upper intestine, known as stomach and duodenal ulcers, require acid suppression to support healing
- NSAID-induced ulcers — ulcers caused or worsened by painkillers such as ibuprofen; Lanzol 30 may be prescribed alongside NSAIDs for protection
- H. pylori eradication — used in combination with antibiotics (triple therapy) to eliminate the Helicobacter pylori bacterium responsible for peptic ulcers
- Zollinger-Ellison syndrome — a rare condition called Zollinger-Ellison syndrome leads to excessive stomach acid. Higher doses are used to manage it, always under specialist supervision
- Acidity and indigestion — symptomatic relief where excess acid is the underlying cause

Safety Advice
Drug interactions
Lanzol 30 interacts with several medicines. Do not take it alongside atazanavir or rilpivirine (used to treat HIV), methotrexate (used in cancer or rheumatoid arthritis), or warfarin (a blood-thinning medicine). Because interactions can affect safety and treatment outcomes, all medicines — including herbal supplements and over-the-counter products — should be shared openly with your doctor and pharmacist.
Alcohol
Avoid alcohol whilst taking Lanzol 30. Alcohol increases drowsiness and can stimulate excess stomach acid production. Treatment effectiveness is reduced and the likelihood of side effects is increased when these interactions occur.
Liver conditions and Chromogranin A testing (Test for neuroendocrine tumours )
Tell your doctor if you have or have had any of the following. If a Chromogranin A (CgA) blood test is scheduled, your doctor should be informed in advance. Lanzol 30 can raise CgA levels and affect test results. Temporarily stopping the medicine prior to testing may be advised by your doctor.
Long-term use risks
Prolonged use of Lanzol 30 may lead to low magnesium levels, low vitamin B12, and an increased risk of bone fractures, particularly of the hip, wrist, or spine. It is also associated with a higher risk of C. difficile diarrhoea. During long-term treatment, regular blood tests may be arranged by your doctor to monitor for these effects.
Driving and operating machinery
Lanzol 30 can cause dizziness. Only when full alertness is confirmed should driving or operating heavy machinery be attempted. Contact your GP if you notice any dizziness or unsteadiness after taking this medicine, and stop driving at once.
Pregnancy and breastfeeding
Because complete safety evidence during pregnancy remains unavailable, Lansoprazole use in this period requires careful consideration. Prompt consultation with your doctor is essential if pregnancy is planned, confirmed, or breastfeeding is ongoing. A careful assessment of the benefits and risks will be carried out by your doctor before any treatment guidance is given.
Accessing Treatment Responsibly
Patient safety and appropriate clinical oversight are safeguarded by this legal requirement.
If you are accessing Lanzol 30 through an online pharmacy, confirm that the pharmacy is registered with the MHRA and displays the EU common logo for verified online pharmacies. Purchasing medicines from unregulated or unverified sources carries serious health risks.
Before starting, stopping, or adjusting any treatment, a qualified UK healthcare professional should always be consulted. See available treatment options for acid reflux and digestive health.
